Treatment facilities in Pennsylvania that process oil and gas wastewater are discharging radioactive elements and salts into streams and rivers, according to preliminary research from Duke University.
The trace metals and radioactive elements have settled and built up in the sediment beds over time, with significant implications for the environment, said Avner Vengosh, a researcher at Duke University who has previously published on water contamination by shale gas development in the United States. He was presenting at a meeting of the Geological Society of America here from ongoing, unpublished research.
